NTG5*1 (NTG5.1) Audio20 is the factory radio unit from Mercedes A-Class, B-Class, E-Class, ML, SLC, GLA and CLA models produced from 2015 to 2019. It is available in a version without navigation (NTG5*1 BASE) and with navigation (NTG5*1 CD).
On the rating label you will find the Panasonic logo. The serial number begins with PA1431, PA1432 or PA1433, and after “Ref. no.” there is CN-MP.., CN-SP.. or CQ-SP.. The digits 520 denote the BASE version, and 522 the CD version.
In your enquiry, please provide the part number from the label (e.g. A 246 900 23 18) and describe what happens when it is switched on: whether the logo appears, the screen stays black, or the fan can be heard. Send the removed module itself for service.
Customers describe these faults in different ways, but they all have one thing in common: an audible fan noise. We confirm the cause after checking the module.
The screen stays black all the time, the CD does not go in, but the fan still runs. The cause may be an internal memory fault: a defective memory chip or errors stored in memory. We confirm this after checking the module.
At first the radio only started after some time, even after around 30 minutes, and now it does not switch on at all. We check the internal memory and, if necessary, replace the chip while preserving the radio data.
The radio switches on briefly, shows the logo and then restarts, over and over again. After checking the module, we determine whether the internal memory is the cause.
The radio gives neither picture nor sound, and on the display in the instrument cluster, in the “trip, phone and navigation” menu, only lines are visible. We confirm the cause after checking the module.
We also repair units with a faulty keyboard or eject button, a damaged CD mechanism, or no navigation function. We confirm the scope of repair after checking the module.
We remove faults in the internal memory, both hardware and software. We confirm the scope after checking the module.
If the memory chip has to be replaced, we do it while preserving the radio’s original data, including its coding.
After the repair, we check whether the unit starts up and works properly, then send it back securely packaged.
We repair your unit instead of replacing it with another one, and we preserve its original data.
When NTG5*1 Audio20 does not start, customers report a black screen, a working fan, occasional logo display, constant restarts and problems with the CD mechanism. Such symptoms may result from problems with the unit’s internal memory, including hardware damage to the memory chip or software errors.
In your enquiry, describe exactly what happens when it is switched on: whether the logo appears and it restarts, whether the screen stays black, whether the fan runs, and whether the CD mechanism does not respond. Also provide the information from the label: model NTG5*1 CD or NTG5*1 BASE, serial prefixes PA1431, PA1432 or PA1433, and any reference number from the housing; this will help with the initial identification.
We repair internal memory defects and remove software errors stored in memory. If the damage requires the memory chip to be replaced, we carry this out while preserving the radio’s original data and the unit’s existing coding.
After the repair, we check whether the unit starts up and returns to working order.
Repairing your own unit allows its original radio data to be preserved, including the coding, even when the memory chip has to be replaced.
If after the repair the unit needs to be matched to the car again, we will help direct you to a workshop that can carry out the synchronisation and adaptation. In your enquiry, mention if the unit has been replaced or modified before, as this will make further handling easier.
You do not need to bring the vehicle in. Describe the problem and we will help you work out what to remove and send. After inspection, you will receive a quote for approval — only then will we start work.
01
Write what is happening in the vehicle, state the make, model and year. Add a photo of the device, the error screen or the nameplate sticker, if you have one. On that basis, we will initially assess whether we can help.
02
Not sure whether to remove the radio, screen, amplifier or another unit? We will advise which component to check, how to prepare it for shipping and how to pack the parcel safely.
03
In the workshop we carry out diagnostics, confirm the source of the problem and define the scope of work. We send a quote for approval. We only start work after your approval.
04
We remove the cause of the fault, test the device and send it back safely packed for refitting. Every repair we carry out is covered by a warranty.

Many thanks to the entire OEMatic team for repairing the radio in my Lexus CT.
Professional and reliable service. I can wholeheartedly recommend this workshop!
Problem: black screen, no working radio, no interaction with the radio at all.

Highly recommended! My OEM JBL amplifier from a Toyota (CHR, 2017) suffered a short circuit, and other audio workshops would not agree to repair it. Here the problem was solved extremely quickly. They received the parcel on Monday, and by Thursday the repaired unit was back with me. Excellent communication at every stage, and most importantly – the price includes a 24-month warranty.
Complete professionalism!

A service absolutely worth recommending. After years of problems with the infotainment head unit in my Skoda Superb constantly freezing and resetting, the MIB was finally repaired. The main dealer could only offer a replacement with a new unit for 3500 eur (!), other car audio companies could not help, and OEMatic carried out the repair in 1 day.

I recommend them wholeheartedly….I don’t know how they did it, but they decoded the radio from an Iveco Daily 2020 faster than it takes to pack the parcel with the radio…One workshop promised a lot, but failed and said the radio was only fit for scrap. I highly recommend them — complete professionalism and a good price. Best regards.

I can definitely recommend them. Mr Tomasz repaired my BOSE amplifiers, RNS, NTG navigation units and more. Always 100% successful, fantastic customer approach and a convenient online platform for placing repair orders.
Piotr BrzezinaRating 5 out of 5. GOOGLE REVIEW
I recommend OEMatic — only 3 days passed from sending the radio to the workshop and having it fitted back in my car.
The radio from a Mercedes ML W164 2007 NTG2 BE 6089 had its fault diagnosed extremely quickly, and the repair was carried out just as fast.
Communication with Mr Tomasz was excellent, and updates from the workshop on the progress of the repair were sent promptly. This is definitely a workshop other people can learn from.
An obvious 5 stars from me.

I had a problem with my Audi A3 8V, with no sound from the factory multimedia player. The guys solved the problem in a few days. I recommend them!

Service and expertise 100%. Thank you for helping with my RNS 315 radio. Highly recommended!

VW Touran radio, I sent it to the company because the reversing camera was not working and the radio would not turn on. Sent by courier. Diagnosis: no faults. (the fault needs to be looked for elsewhere) The radio was sent back quickly and the company did not charge anything, not even for the return postage. There probably aren’t many honest companies like this left here in Poland. Many thanks.

Definitely recommended. Very fast repair and very good, speedy communication. Information was available at every stage of the repair request process — an online repair management system. The unit (radio) was already meant to be written off and replaced with another used one. Fortunately, I accidentally found the OEMatic blog while looking for a replacement, and it saved me from replacing it with another used unit, which would have been a loss for the appearance (the fronts of the replacements I found were not in such good condition, and all of them were older than my unit from pre-facelift models); the newer ones were more expensive than the repair. So that’s a plus too.

RNS 315 radio with faulty Bluetooth. The radio sounds better than new. Others gave up on the repair, OEMatic handled it efficiently and quickly without any problems. We need more professionals like this. Thank you for the repair.

Professionally carried out repair of a factory VW radio, excellent communication, complete professionalism. May there be more companies like this in Poland.
Sławomir PobłockiRating 5 out of 5. GOOGLE REVIEW
I left a Honda Jazz radio panel for repair. In addition to the radio, the guys also repaired the CD player at the same price, even though I hadn’t asked them to. I also received spare bulbs for the button backlighting. Very friendly and professional, the radio and player work flawlessly. I recommend them with a clear conscience. Such expertise is rare nowadays.

Highly recommended. ZENEC radio after the pin was blocked. Code removed. Radio works, old pin. Fast, 1 day. Telephone contact without any problem. Parcel safely packed.

For a long time I’d been battling an annoying problem in my VW Passat B8 — the car radio kept losing sound. Fortunately, I found OEMatic Car Media Lab and it was a perfect choice!
From the first contact it was clear there was professionalism and huge knowledge of factory audio systems. Quick diagnosis and an even quicker (and most importantly: EFFECTIVE!) repair! The result? The radio plays crystal clear, with no dropouts or interruptions. You can tell the fault was removed at the source, not just temporarily masked.
If you have any problems with factory audio, navigation or the radio in your car (especially VW, Audi, Skoda!), I definitely recommend OEMatic Car Media Lab. True experts!

The Harman-Kardon amplifier in my BMW F33 was flooded, so I decided to hand it over to OEMatic. A quick check to see whether it could be saved — yes! it could! A few days later the amplifier was back with me after repair.
For a moment I also had doubts whether only the amplifier had been damaged by the flooding, because I lost the ability to set the time and information such as instant fuel consumption or average fuel consumption disappeared; after a phone call I was told that this can happen because of a break in the car’s CAN circuit due to the amplifier being absent.
The theory proved correct, and fitting the already repaired amplifier helped and all the functions returned.
I hope the amplifier will serve for a long time to come and without faults.
I honestly RECOMMEND IT!

A great company, they will help you in any situation when it comes to navigation.
Two companies from the Małopolskie region where I live suggested replacing the unit; at the authorised service centre the fault repair would cost 1400 ,- and they helped me fix it, and over the phone 😃
Miroslaw SytyRating 5 out of 5. GOOGLE REVIEW
The content of the reviews I read quickly convinced me to have my unit repaired at OeMatic. I expected the highest quality of service at every stage and that is exactly what I received. After the phone call I received all the information needed for shipping by text message. As soon as the workshop received the parcel with the radio, I got a phone call, we agreed the details, I confirmed the price and the repair began. In the afternoon of the next day I was informed that the repair had been completed, I settled the bill and the radio was back with me after 4 days. It seems there is no room for even the slightest shortcoming in this company (such as a delay with a text message).
For me, this is the highest quality.
Thank you very much for the repair and I wish you success🙂

Professional and reliable service. The fault was initially diagnosed remotely, and the repair cost estimated. The unit was delivered to the workshop and collected remotely by courier. Everything was fast, straightforward and efficient. The car audio came back to life 🙂
I can recommend them with a clear conscience.

Five stars is not enough..
OEMatic solved the problem with a non-working USB port (motherboard repair) in the factory navigation system from a Kia Sportage in express mode. Highly recommended.
KJAnswers to questions about Mercedes NTG5*1 Audio20.
Yes, if the fault is in the unit. We identify the cause after checking the module. We also repair the keypad, eject button, CD mechanism and missing navigation function.
We replace the memory IC while preserving the original radio data, i.e. its coding. If in your case pairing with the car turns out to be necessary, we will help you find a workshop that can carry it out.
Yes, it is the same family of units. The numbers 520 on the sticker mean NTG5*1 BASE without navigation, and 522 means NTG5*1 CD with navigation.
The absence of a number on the site does not rule out repair. Send a photo of the label and the Mercedes model, and we will check whether it is NTG5*1 Audio20.
No. If you decide not to proceed, if the unit cannot be repaired, or if the fault lies elsewhere, diagnosis and return shipping are free of charge. We start the repair only after you approve the scope and the price.
Software or hardware fault? For us, it makes no difference — we successfully repair 95% of damaged NTG5*1 Mercedes navigation systems.
